ELECTRICALLY-PR OPELLED VEHICLE FOR SINGLE-RAIL ELEVATED RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 700,609, dated May 20, 1902.

Application filed February 24, 1902. Serial No. 95,408. (No model.)

ways, of which the following is a specifica-' tion.

My invention relates to electrically-propelled vehicles for single-rail elevated rail-.- ways, so constructed that the passenger ac-.

commodation is free from side to side, that the vehicle can easily travel along curves of comparatively small radius, and that the heavy parts,including the electric motors,are arranged at a low level, giving great stability, as I shall describe with reference to the accompanying drawings, in the several figures of which the same letters are employed to denote the same parts.

Figure-1-is a side elevation, and Fig. 2 is a plan, of a vehicle according to my invention.

Fig. 3 is a side elevation with the side of the vehicle removed, and Fig. 4 is a plan with the fioor removed of one of two bogies on which the motors and driving mechanism are mounted. Figs. 5 and 6 are transverse sections, respectively, on the lines 5 5 and 6 6 of Fig. 2; and Fig.',7 is a transverse section of the upper part of the vehicle on the line 7 7 of Fig. 3.

a is the body ofthe vehicle, which is arranged to accommodate passengers with free passage from side to side. It is pivoted at two points on journals b, projecting up from two bogies which carry the motors, the propelling mechanism, and the guide and conducting wheels. The body has under its floor eight bearing-pieces c, which rest on eight rollers d, placed. atanangle and mounted on springs s on the bogie-frames. Thus the two bogies, each-of which carries a driving-wheel e anda trailing wheel f, can turn a little horizontally under, the body on the pivots 1), al-

carries two electric motors g, one on each side.

jtors of each bogie.

sleepers n.

On each of their shafts are two sprocketwheels connected by flat chains 71. with wheels on the shaft 71 of the driving-wheel 6, each of the two driving-wheels being thus driven by four chains from the shafts of the two mo- On each bogie are also mounted the eight horizontal wheels j, which run on the lateral guide-rails, the vertical axles of these wheels being pressed against therails by springs 70. There are also mounted on each bogie'four conducting-Wheels Z, two on each side, running on conducting-rails m, which are mounted on insulators fixed on The axle-boxes of the'wheels Z slide in horn-plates p, in which they are pressed down-by helical springs.

Although I have shown and described a number of driving, lateral guiding, and conducting wheels suited for a vehicle of the dimensions shown, obviously the number of these wheels might be varied to suit vehicles of different dimensions, maintaining, nevertheless, the general construction and relative arrangement of the body and the bogies as described and illustrated.

Having thus described the nature of this invention and the best means Iknow of carrying the same into practical efiect, I claim- An electrically-propelled vehicle for a single-rail elevated railway, comprising a body for accommodation of passengers, pivoted and mounted on' spring-urged angle-rollers on bogies, which carry in the middle drivingwheels and at the sides electric motors connected by chain gear to the driving-wheels which also carry at the side spring-urged lateral guide wheels and conducting Wheels pressed by springs on a conducting rail mounted on insulators, substantially as described.

In testimony whereof I have hereuntoset Witnesses:

DAVID WILLIAMS, WALTER E. ROCHE.
